Alarm time                            Class   Description
2012-10-09 20:39:23 IST   Minor      Host 0 Boot from secondary firmware

 

As provided by the description, the probable cause is that the host has booted up from secondary firmware (RE BIOS firmware), rather than the primary one.

 

To resolve this issue, perform the following procedure via the SRX device's CLI:

1. show system firmware: This command will display the current firmware.

Part             Type          Tag     Current    Available Status
                                       version    version
Routing Engine 0 RE BIOS        0      1.9        2.1       OK
Routing Engine 0 RE BIOS Backup 1      1.9        2.1       OK

2. request system firmware upgrade re bios - This command will upgrade the RE BIOS.

root>run request system firmware upgrade re bios
Part             Type            Tag  Current Available Status
                                      version version
Routing Engine 0 RE BIOS         0    1.9      2.1      OK
Routing Engine 0 RE BIOS Backup  1    1.9      2.1      OK
Perform indicated firmware upgrade ? [yes,no] (no) yes

When the upgrade has successfully completed, the new BIOS will take effect, after the device has rebooted. After waiting for about three minutes for the primary firmware to be upgraded, you can initiate the upgrade for the secondary firmware.

3. request system firmware upgrade re bios backup - This command will upgrade the REs backup BIOS as well.

root>request system firmware upgrade re bios backup
Part             Type              Tag Current Available Status
                                       version  version
Routing Engine 0 RE BIOS           0    1.9        2.1   UPGRADED SUCCESSFULLY
Routing Engine 0 RE BIOS Backup    1    1.9        2.1   OK
Perform indicated firmware upgrade ? [yes,no] (no) yes

When the upgrade has successfully completed, the new BIOS will take effect, after the device has rebooted.

Note

• You will have to reboot the node, after the upgrade is complete.

• The SRX650 device does not have backup firmware.
